Marantz UD5007, no more YouTube

The UD5007 is a discontinued item.  Unfortunately, Marantz has no control over how or when Youtube/Hulu/etc. change their streaming protocols.  It's not in any company's best interest to continue to redevelop firmware on discontinued products to keep up with changing technologies (since they are no longer selling that product).  Even Oppo is getting out of the streaming business with their latest 20x series players.

Your best bet is probably to get either the Amazon FireTV unit or a Roku.  Both Amazon and Roku are in the business of supporting many streaming services and this will keep you current on any changing or new technologies.  The Amazon Fire has a very high quality app for Youtube (both high quality video and audio transfer).

Some thoughts to keep in mind....

I have both an older Sony BDP-S590 bluray and also an Amazon FireTV. I don’t know the current Sony app offering, but the YouTube app on my particular Sony is not that good. It really only give you standard definition video and the audio side is not really high-def. Also, the Sony bluray players are somewhat soft sounding as a transport. Sony will stop doing firmware updates for a product within a year after it has been discontinued. I have not had a firmware update for my BDP-S390 in a very long time.

The Amazon Fire TV is an open platform (based on Linux I think) just like their Fire and Kindle tablets. It has constant app updates with a huge collection of online apps to choose from. My FireTV is one generation old, but still is able to get both YouTube and core FireTV O/S updates. The YouTube app is superior over the Sony both in usability and capability to do hi-definition and hi-resolution audio. It will provide this over HDMI to your processor. You can also stream Amazon video content.

I have tested both of these devices directly connected to my Krell S-1200 processor through HDMI.
